Cobalt Lathe Tool Blank 1/2 in 4 in

This Cleveland Golf C44551 lathe tool blank is made from M42 cobalt steel. It measures 1/2 inch wide by 1/2 inch high and 4 inches long. The non-beveled blank suits right-hand and left-hand turning operations. Machinists and toolmakers use it to grind custom cutting tools for specific lathe work.

Build integration: custom grinding stock

The blank provides raw material for shaping bespoke tool profiles on a bench grinder. Its square cross-section fits standard tool holders without modification. M42 cobalt content maintains hardness at elevated cutting temperatures. Users free themselves from catalogue geometry limits by grinding only the angles their job requires.

Suits custom tool grinding, not ready-to-use cutting

This blank serves shops that grind their own turning tools for one-off or short-run parts. It does not suit operators who need pre-ground inserts with chipbreakers or coated edges. Buyers wanting indexable tooling systems should look at dedicated insert ranges instead.

Questions about this item

How long does the 1/2 in square cobalt blank hold an edge before it needs regrinding?

The M42 cobalt steel retains hardness at high cutting temperatures, extending edge life during sustained lathe work on tough alloys.

Does the 4 in blank run hot or vibrate during continuous turning?

The solid 1/2 in square cross-section acts as a heat sink and dampens chatter, keeping the tool cool and stable in long sessions.

What holder or tool post is needed to clamp this 1/2 in square blank?

Any standard quick-change tool post or four-bolt tool holder with a 1/2 in square pocket will secure the blank without adapters.
